Abstract
A minute pulse switch, essentially characterized in that the pulsation member is hollow, and forms the inverted and mobile cylinder of a piston, which is fixed by its tubular rod, to the bottom of a terminal box embedded in the wall ; inside the tubular stem, a strong spiral spring is housed, which extends superiorly to wind around a needle centered with the pulsating cylinder; this cylinder has a protruding flange around its mouth, which forms a stop and is retained with the cover washer of the recessed box, the washer being fixed with the box, by means of screws.
